R devel - Mar 2014 - rgl question

Hello,

If I call lines3d(x,y,z) I get lines connecting each point, but
when I call rgl.lines(x,y,z) I get dashed lines, and adding
something like type='l' leads to an error message. The
docs seem to suggest that rgl.lines() calls lines3d(), so
I would expect the result to be the same.

Any tips would be appreciated.

Thanks,
Dominick

The difference is in how they use the material properties:  rgl.lines 
sets them permanently, lines3d restores the original value after the 
call.  So I'd guess your call to rgl.lines followed a call to another 
rgl.* function that set the lty property to dashed.
